Watching Whales Watching Us - NYTimes.com: "The sperm whale, for example, which has the largest brain on earth, weighing as much as 19 pounds, has been found to live in large, elaborately structured societal groups, or clans, that typically number in the tens of thousands and wander over many thousands of miles of ocean. The whales of a clan are not all related, but within each clan there are smaller, close-knit, matriarchal family units. Young whales are raised within an extended, multitiered network of doting female caregivers, including the mother, aunts and grandmothers, who help in the nurturing of babies and, researchers suspect, in teaching them patterns of movement, hunting techniques and communication skills. “It’s like they’re living in these massive, multicultural, undersea societies,” says Hal Whitehead, a marine biologist at Dalhousie University in Nova Scotia and the world’s foremost expert on the sperm whale. “It’s sort of strange. Really the closest analogy we have for it would be ourselves.”"
